New fifth wheel drove home need to return to dealer

If the OP likes the 5th wheel, he may find it cheaper to rent a space in a public storage area to keep it instead of at his home. I did this for a number of years when we lived in Colorado.

Other possibilities is to reshape the yard area where you are trying to park at home. Sounds like you have a hump you are trying to back over. There are lots of things I would try before I lost roughly $5,000 on a rig I liked other than the jacks digging into the dirt.
